WALTER S. ADAMS, OF PHILADEIJPHIA, PENNSYLVANIA, ASSIGNOR TO THE J. G. BRILL ice.

OOANY, OF PHILADELPHIA, PENNSYLVANIA, A

VANIA.

To all whom it may concern:

Be it known that I, WALTER S. ADAMS, a citizen of the United States, and a resident of the cit and county of Philadelphia and State of Ionnsylvania, have invented certain new and useful ster-Guides, of which the following is a speclfication.

The object of-this invention is to provide a device of this classwhich will eliminate the necessity of using chafing plates between a car truck bolster and truck transoms, keep the bolster a fixed distance from the transoms but yet allow the usual movements transversely of the truck and otherwise as may be required by the conditions of serv- These and other objects are accomplishedby my invention, a more particular description of which will appear below.

Reference is to be had to the accompanying drawings in which Figure 1 is a plan View of a portion-of a car truck to which my improved bolster guide is applied, portions of the truck being shown in dotted lines; Fig. 2 is a front elevation of the same; Fig. 3 is a plan view of a different form of truck to which my invention has been applied; Fig. 4'is a front elevation of the same; Fig. 5 is a sectional view on the line 5-5 of Fig. 3 looking in the direction of the arrows; Fig. 6 is a. side elevation of one of 'the pins upon which the guide link is mounted; Fig. 7 is a perspective view of a bracket; Fig. 8 is a sectional view of the end of the guide link and bearing with bearing cap; and Fig. 9 is a plan view of a bearing cap. Throughout the several views of the drawings, similar reference characters designate similar arts. 1

The car true to which my invention may be applied may be of conventional or desired construction and is provided with side frames 1 and transoms 2, said transoms being suitably united by a tie bar 3. Gusset plates 4 also secure the transoms to the side frame 1, said gusset plates being secured thereto by bolts 5.

. A bolster 6 is mounted between the transoms upon suitable springs. In Figs. 1', 2 and 3 it is mounted upon leaf springs 7between the ends of which are mounted coil springs 8 with caps 9. In Figs. 3, 4 and 5. the bolster is mounted upon leaf springs 10, on top of which are mounted coil springs 11,

the bolster being supported on said coil springs. To hold the bolster free and keep it out of contact with the transoms mechanism may be used which will now be de-- scribed.

Referring to the construction shown in Figs. 1 and 2. Secured to the bolster 6 by means of bolts 12 or other equivalent means, Extending through a conical perforationin said U-shaped bar 13 1s a pin 14, having a practically spherical a head 15, a tapered portion below said head and a screw threaded end 17 upon which are mounted a nut '18 and lock washer 19 securing the pin in place. The tapered portlon 16 of the pin 14 fits into the conical perforation in the U-bar 13 above mentioned. Secured to one of the transoms by bolts 20 is a bracket 21 having a fiat portion 22, by which it is secured to the transom, and an upright portion 23. The upright portion 23 has a conical perforation 24 and angled corners 25. Mounted in the conical perforation is a pin 14, identical with the pin 14 before mentioned and having the spherical head 15, tapered portion 16, threaded end 17, nut 18 and washer 19. Extending between the two pins 14 is a link 26, said link being made up of two parts 27 between which are a number of plates 28. The plates 28 and parts 27 are held together as one unit by bolts 29. The link 26 thus made has two perforations shaped to fit the spherical heads 15 of the pins 14. From the foregoing it will be seen that the link 26 extending between the pins 14 and mounted upon the spherical heads 15 prevents the bolster from coming into contact with the transoms while at the same time, the spherical heads act as universal joints for the link 26 and allow the bolster'a free up and downamovement and movement transversely of the truck. The corners 25 on the bracket 21 are angled to prevent the link from contacting therewith during movement of the bolster. The wear at the joints may be regulated by removing some of the plates 28 from the link 26.

In Figs. 1 to 6 it will be noted that the spherical heads 15 on the pins 14 are not entirely spherical, their outer ends being fiattened. In Fig. 8 I have shown the pins 14 provided with complete spherical heads 31. Secured to the link 26 are caps 32 which fit over the tops of these heads 31, these caps CORPORATION" OF PENNSYL- comprising a central dome 33, having an opening 33 for lubrication, which fitsthe end of the head 31 and ears 34 having perforations 3 L through which extend rivets or bolts 35 securing the cap to the link 26. The rivets or bolts 35 do not extend through the entire link but only through one of the outer portions 27 as shown in Fig. 8.

In the structure shown in Figs. 3, 4 and 5, a bracket 30 extends upward from the bolster and in which is mounted the pin 14. Another pin 14 is secured to one of the transoms and the link 26 above described extends between these pins 14, the link in this instance being with its widest side uppermost as shown.

From the foregoing, the operation of my improved device will be readily understood. The link prevents the bolster from contacting with the transoms, thus obviating the necessity for the chafing plates usually used thereon, but readily allows an up and down movement of the bolster or a movement of the same transversely 'of the car truck.

The bolster guide is, of course, duplicated at both ends of the bolster, or at appropriate points along the length of the bolster; and instead of having the bolster guides extending in the same direction, they may extend in directions opposite to each other.

From the foregoing description of my invention, it is obvious that the same is not restricted to the precise embodiment shown herein, but is broad enough to cover all structures coming within the scope of the annexed claims.

Having described my invention, what I claim is:

1. In a car truck, a frame, a bolster movable in said frame, a bearing comprising a spherical projection on said bolster, a bearing comprising a spherical projection on said frame, and a link variable in thickness with relation to said bearings extending between said bearings and mounted thereon.

2. In a car truck, a frame, a bolster movably mounted within said frame, a bearing on said bolster comprising a pin having a spherical head, a like bearing mounted on the truck frame and a link variable in thickness with relation to said bearings extend-" ing between ,said. bearings and movably mounted thereon.

3. In a car truck, a ably mounted within said frame, a bearing on the bolster comprising a pin secured thereto having a spherical head,a like hearing secured to the truck frame, and a link variable in thickness with relation to said bearings extending between said bearings and having perforations fitting over said spherical heads and allowing a movement of the link thereon.

4. In a car truck, a truck frame, a bolster movably mounted within said frame, a bracket on the bolster, a pin having a spherical head mounted on' said bracket, a

bracket on the truck frame, a. pin having aspherical head mounted on said bracket and a link comprising two outer parts with a series of plates between them having perforations adapted to fit over said spherical heads extending between said pins.

In a car truck, a truck frame, a bolster movably mounted within said frame, a bracket secured von the bolster, a pin secured in said bracket having a spherical head; a bracket secured to the truck frame, a pin secured in said bracket having a spherical head and a link comprising two outer parts and a series of plates between said outer parts, said link extending between the spherical heads and having perforations fitting over said heads and allowing movement of said link. n

6. In a car truck, a truck frame, a bolster movably mounted within said frame, a hearing comprising a spherical projection on said bolster, a bearing comprising a spherical projection onsaid frame, a link variable in thickness with relation to said bearings extending between the-same and having perforations fitting over said spherical heads and allowing a movement of the link thereon and caps secured to said link and fitting over the portions of the bearings extending outside of the perforations in the link.
